What kind of wiring system does a 1964 Pontiac GTO have?

What kind of wiring system does a 1964 Pontiac GTO have?

The wiring systems of the 1964– 1974 Pontiac GTOs are probably closer in complexity to a Model T Ford than anything currently in showrooms. While that may be true, wiring systems are still a point of fear and loathing among many restorers of Pontiac GTOs and other muscle car era machines. The truth is, it really isn’t that bad if you plan ahead.

What causes a wire to come out of a GTO?

Sometimes, it is a simple fix, as when a wire was pulled and stretched enough that it came out of the back side of a plug-in connector. Perhaps a plastic wire insulator cracked with age and exposed a bare wire to some bare metal and a short was caused. Keep an eye out for obvious prob­lems like that.

Do you need ground straps on a 1974 GTO?

Unibody cars do not have this level of reliance on ground straps like a conventional body-on-frame design, but even the stub-framed 1974 GTOs need them more than a modern car. A wiring diagram from your shop manual lists the number of ground­ing points and their locations.

Why is my GTO not getting enough power?

Problems can usually be traced to a switch fail­ure, break in the wiring connection, faulty ground, or defective device, be it a bulb, motor, or radio. Use your multi-tester to see if power is actu­ally getting to the device. If it is, the device is malfunctioning. If not, look for the connection failure.

What to do if your GTO wiring is not complete?

Use a multi-tester to make sure that all the wiring is still func¬tional and replace the wiring that does not complete a circuit. Simply connect the multi-tester’s probes to the connections to see if current passes though the wiring. If it does, the gauge on the face of the multi-tester moves to show the current flow.

How can I tell if my GTO multi tester is working?

Simply connect the multi-tester’s probes to the connections to see if current passes though the wiring. If it does, the gauge on the face of the multi-tester moves to show the current flow. If if doesn’t, it stays at zero.

What kind of engine did a Pontiac GTO Judge have?

Judges received psychedelic “The Judge” decals on the front fenders and rear airfoil. “Ram Air” decals on the hood scoops denoted the standard 366-hp engine and “Ram Air IV” callouts, the optional 370-hp engine. Judges sported a tri-colored side stripe that ran from the front fender to the rear edge of the quarter window.

What was the length of a 1969 Pontiac GTO Judge?

Its heads now featured larger intake ports to complement the already larger-than-a-D-port round exhaust ports. The 308/320-degrees advertised duration 041 cam from the Ram Air II was retained, but new higher ratio 1.65:1 rocker arms increased lift to .516/.516 from .470/.470-inch.

What kind of car is the Pontiac GTO?

Pontiac GTO. The Pontiac GTO is an automobile that was manufactured by American automobile manufacturer Pontiac from the 1964 to 1974 model years, and by GM’s subsidiary Holden in Australia from the 2004 to 2006 model years.

When did I change the alternator on my Pontiac?

PONTIACS HAVE CHANGED THE BRACKET CONFIGURATION + THE NUMBER OF WATER PUMP BOLTS OVER THE YEARS. I ENDED UP WITH BRACKET FOR 1968,1969, & 1974. NOTHING WOULD WORK WITHOUT BIG MODIFICATIONS. I AM STILL TRYING TO BOLT THE ALT. AND POWER STEERING JUMP TO THE PONT. ENGINE AND THEN ADAPT TO THE EL CAMINO BODY. “AIN’T” HOT RODIN FUN ! ! !

What kind of power steering does a 66 GTO have?

Not too exciting, unless you’re trying to figure out how the brackets bolt together on your car. The following 4 photos are of my ’66 GTO, but the engine is a ’72 400, so the brackets and power steering pump are 70’s style.

What causes a radiator alternator to stop working?

A closer observation of the radiator will reveal a system of pulleys or belts that work to convert mechanical energy into electrical energy. The alternator will stop working the moment your belt wears out and breaks or the pulley becomes damaged. These items are easy to replace. 3. Faulty fuse Fuses blow up due to a power surge or they wear out.

Can you drive a car with a faulty alternator?

Faulty diodes can easily be replaced, but you will need to dismantle the alternator. It is impossible to drive the car with a faulty alternator. While it is the work of the battery to power the electrical components in the car, it cannot do this alone.

What happens when the belt on an alternator breaks?

A closer observation of the alternator will reveal a pulley and belt system that works to convert mechanical energy into electrical energy. The serpentine belt powers the alternator, and if it fails, the alternator will stop working the moment your belt wears out and breaks, or the pulley becomes damaged.

What is the function of an alternator in a car?

The main function of the alternator is to power the car’s battery. When your AC, headlights, and stereo are on, a lot of power is needed. The battery cannot supply all this power on its own, hence the need for the alternator. The alternator converts mechanical energy into electricity.

When did the Pontiac GTO Trans Am Come Out?

But the GTO was not the only cult car, which came out in the 60s under the Pontiac logo. In 1967, another American car saw the light – Pontiac Firebird, a direct competitor Dodge Challenger and Mercury Cougar. Soon, in 1969, came Firebird Trans Am. Both the car continued to be produced at GM ‘s plant until 2002.

What kind of starter system does a Pontiac V-8 have?

The cranking system of a Pontiac V-8 (and all similar GM vehicles) consists of: 1. Battery and two battery cables 2. Starter motor 3. Starter solenoid 4. Electrical starter controls (See drawing for a typical starting system.)

What to do if your Pontiac starter does not turn?

The solenoid operates but the starter does not turn (you can hear the solenoid click on when the start circuit is energized). Assuming the starter motor is okay, the switch portion of the solenoid is defective. A temporary repair can be made by disassembling the solenoid, filling/cleaning the switch posts and switch disc.

Use a multi-tester to make sure that all the wiring is still func¬tional and replace the wiring that does not complete a circuit. Simply connect the multi-tester’s probes to the connections to see if current passes though the wiring. If it does, the gauge on the face of the multi-tester moves to show the current flow.

What kind of starter motor does a Pontiac have?

The starter motor is a very high current and powerful direct drive electric motor that rotates and turns the engine via the ring gear (flex plate) when the solenoid operates. The starter includes the starter drive gear that is equipped with an over-running clutch.

Where are the grounding points on a GTO?

A wiring diagram from your shop manual lists the number of ground­ing points and their locations. If they are missing or no longer functional, correct replacements are available. Once the grounds have been attended to, it is time to move on to the other connections in the car.

Why is my GTO engine no longer working?

Over the course of 40 or more years, it is likely that your GTO, like any vehicle that age, has developed some wiring problems. Perhaps the backup lamps no longer work or a power window is no longer opera­tional, and maybe the engine won’t fire.

Why are the jumper cables on my GTO not working?

Of all the electrical connections on your GTO, chances are that the battery cables and terminals have seen more use and abuse than any other part that carries current. Often, the terminals have been overtight¬ened and distorted. Also, jumper cables have gouged them and battery acid has cor¬roded them.
